When I've done this in the past, there is no dictionary item for elements that aren't specified explicitly. so i've always had to do: config.get('user_code_runner', 'restish'). Seems odd/annoying juju wouldn't do that for me, so maybe you know a trick

  user_code_runner:
    default: "restish"
    type: string
    description: The user that runs the code

So it's guaranteed to at least set to 'restish'.
